HAT-HARDENING MACHINE.

ClPECIPICATION forming part of Letters Patent No. 350,129, dated October 5, 1886.

Application filed Au'g'ust 25,1885.

To all whom it may concern.-

Be it known that I, DENNIS II. HAGGER'IY, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in I Iat-Hardening Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will. enable others skilled in the art to which it appertains to make and use the same.

My invention relates to the manufacture of hats, and has for its object to produce a machine that will harden and solidify the hatbodies immediately after their removal from the cone.

lleretofore it has been the custom to take the hats directly from the forming room to the sizing-machine; but this is objectionable for the reason that the stock is very gr-ecu, and the bodies are easily destroyed. In order to obviate thisobjection I have devised a machine l'or hardening the hatebodies, which I preferably place in the forming-room. The hats are taken directly from the cone and placed in this machine, which I will now de scribe, referring by letters to the accompanying drawings, forming part of this specification, in which Figure 1 is an end elevation of the machine complete; Fig. 2, a plan view of the same; Fig. 3, a cross-section of one of the rollers or cylinders on the line at 00; Fig. 4, a cross-section of one of the rollers or cylinders on the line y y, looking toward the left, and showing the attachment of one of the trunnions; Fig. 5, a view of a modified form of lag; Fig. 6, aside View of the same, and Fig. 7 a view of still another form of lag.

Similar letters indicate the same parts in all the figures.

A is the framework in which the rollers are journaled, and Aextension-arms in which the drivingsha-ft is journaled.

B B are the two under rollers or cylinders, which are perforated, and tilled with. steam by means of pipes N.

O is the top roller, which. maybe se1ni-('-ylindrical in form. This roller is solid, as it is essential that its own weight should keep it in operative position.

Serial No. 175,273. (No model.)

C is the fiat portion of roller 0.

D is the driving-shaft, and 1D is the crankdisk, which imparts to the three rollers oscillatorymotionby means of a link, F. One end of this link is secured at theedgeot' the crankdisk by a serew-pin, F also acting as a pivot for the link, the other end of which is fastened to a crank, F, by means of a pin, F. This crank has a collar, F which engages one olthe trunnions of the right lower roller. (See Fig. 1.) This trunnion is provided with a spline or feather, which prevents the collar from turning thereon.

G is a tank placed under the rollers for the purpose of catching the waste water that is pressed out, and is secured to the framework in any suitable manner.

H is a foot-board attached to twolevers, II, which are pivoted to the under cross-pieces of the frame-work, and pivoted again at their ends to bars or rods Il These levers, when pressed downward, act to tilt the bell-crank levers I, which in turn raise the top rollers. These bell-crank levers have collars l, which turn. on the shalt I? of the right lower roller when it is desired to lift the roller 0. The upper ends of levers I also have collars If, in which the shaft Q, of the top roller is journaled.

I1 is a pin acting as a stop to one of the le vers' H, which prevents the top roller from, dropping down so far as to come in contact with the other rollers.

K represents sprocket-wheels, which operate the lower rollers by means of the belt or chain L, which passes around them. This belt passes around the two sprockets on the right side of the machine. (See Fig. 2.) On the opposite side I place a sprocket, K, on the top shaft, and :another, K", on one of the lower shafts. A belt or chain, L, passes over these two sprockets, and thereby imparts motion to the upper roller. If belts are used, they are provided with holes If at certain distances apart, which engage the sprockets on the wheel.

, M M are lags, which are fastened to the rolls in any suitable manner, as by screws or bolts. These lags may bemade strai ght upon the rollers or placed on them. at an anglethat is, as shown in Fig. 5. The form which I have shown in this figure I make of metal, wood, hard rubber, or

any suitable material, with a base-plate, M, which is screwed to the rollers. This plate is made slightly curved, so as to fit the cylinder, and after it is fastened to the roller another one is placed close up to it and fastened, and so on around the cylinder, until it is entirely covered. Should a lag get broken in use, it can be taken off and another one put on with only an instants delay. The lag is also provided with perforations M, which, when the roller revolves, permit the water to run off and not remain in the groove.

In the form illustrated in Fig. 7 the lag is made solid, and is attached directly to the base-plate. This lag is made narrowest at the center, the two ends being the widest portions, and the sides inclining outward evenly from center to ends, the tendency being to work the stock slightly inward toward the center. The steam is admitted to the two lower rollers or cylinders by means of pipes N. I These pipes simply pass into the cylinder through the trunnions and there discharge the steam, which escapes in direct contact with the hat through the perforations O in the top of the cylinders, thus keeping the hats always wet and warm.

I? indicates the trunnions of the right lower roller, one of which is made hollow to permit the steam-pipe N to passinto the cylinder; and Q, the trunnions of the left lower roller, which are constructed in a similar manner to trunnions P.

Ris the shaft of the top roller, whichis journaled in the collars I of the bell-crank 1evers I. Y

P is a flange upon the trunnions, which is securely bolted on the inside of the cylinderheads, as shown in Fig. 4. The top roller is solid, as above described, and its shaft R passes directly through the roller and bears in the collars of. the bell-crank levers, as above described.

'S is a table upon which the operator prepares the hats for hardening. This table is held in position by a bracket, S, which is secured to the tank. I I

The operation is as follows: After the machine is started the operator takes the hats as they are removed from the cone, squeezes the water from them, places them upon the table S, and rolls them up in. the desired manner. The foot-lever His then pressed downward. This acts to tilt the bell-crank lever I, whose collar 1 bears on the shaft P, one of the lower rollers thuscausing the upper roller, 'C, to be raised sufficiently to allow the roll of hats to be placed in the position shown in Fig. 1- that is, between the thre'erollers, The action of the machine is to rock the hats back and forth, with steam continually coming in contact with them, which has atendency to harden'and shrink them, so that when they are taken to the sizing-room they will not be so easily broken or need to be so carefully hand le'd, thus saving considerable time in the handling, and preventing the serious loss to the manufacturer which hasheretofore resulted manner.

from the injury or destruction of the bodies before they reached the sizing-machine. Motion is imparted to the rollers from a shaft, D, which may be driven in any convenient This shaft has on one end the crankdisk E, provided at its outer edge with a pin, F, which acts as a bearing for the link F. The other end of this link is secured to the crank F by screw or pin F. This crank has a collar,

which engages shaft 1?, being held by a spline,

as described above. As the crank-disk revolves, it carries link F around with it. This in turn causes crank F to oscillate, which, be-

ing fastened firmly to shaft I, will impart to said shaft an oscillatory motion, andas the two lower rollers have sprocket-wheels K on their shafts, and are connected by a belt or chain passing over said spockets, both lower rollers are thus caused to rock back and forth as the crank F oscillates. The upper roller is caused to rock in the same manner by means of a belt or chain, L, and sprocket-wheels K K, with which it engages, It will thus be seen that all of the rollers have the same motion.

Their action is to harden and solidify the stock in the hat-bodies, so that they may be handled without danger of breaking or tearing them.

I do not desire to limit myself to the exact details of construction shown, as it is obvious that they may be varied within reasonable limits without departing from the spirit of my invention.

I am aware, however, that angular lags not perforated and not made integral with the baseplates have been made prior to my invent-ion.

Having thus described my invention, I claim-- 1. In a hat-hardening machine, a series of rollers between which the'hats are placed, one of which may be lifted from its normal position, and meansas a pivoted link connected to the driving-shaft, and sprocket-wheels upon the roller-trunnions, connected by chains or I belts-whereby an oscillatory motion is impa rted to the rollers. I

2. The rollers, one 'or more of which'have hollow trunnions through which steam is admitted, and perforations through which it escapes in direct contact wit-h the hats, in combination with sprocket-wheels upon the rollertrunnions, belts or chains connecting said I sprocket-wheels, and means-for example, a.

driving-shaft having a erank-disk, link .11, and crank 'Fwhereby oscillatory motion is imparted to the rollers. I

3. The rollers having sprocket-wheels and belts orchains connecting them, in combination with a crank upon the trunnion of one of the rollers, and a pivoted link connecting said crank with a crank-disk upon the drivingshaft, whereby an oscillatory motion is imparted to the rollers, substantially as described. I I I 4. The framework having at'the top on each side an'e'Xtensio'n-arm which supports the main shaft, said shaft having at one end a crankdisk which at each revolution imparts to one ICO IIO

IIS

of the rollers an oscillatory motion by means so that when the crank-disk revolves it will of a link fastened to a crank upon the shaft of said lower roller, in combination with sprocket-wheels connected by belts or chains,whereby the motion-is transmitted to the other roll- (,IS.

5. In a hat-hardening machine, detachable lags consisting of base-plates M, having angular lags M, which are provided with perforations ll/P, as and for the purpose set forth.

6. In a hardening machine, a top roller which may be moved from operative position by the bell-crank lever, in combination with two lower rollers, to which motion is imparted by a crank-disk having a link fastened thereto, said link being also secured to a crank which is securely fastened to one of thelower rolls by means of a key or spline,

cause the rolls to rock back and forth, motion being imparted from one to the other by means of sprockets and chains or belts.

7. In a hardening-machine, two hollow lower rollers having perforations, whereby steam is admitted and brought in direct contact with the hats, and having hollow trunnions which are flanged on the inside and securely bolted to the rollers, in combination with a frame sup porting said rollers, a tank under the rollers, and a table.

In testimony whereof I ailix my signature in presence of two witnesses.
